Obsidian URI set up for Linux / obsidian.desktop

[argentum]

@Craig

extracted obsidian.png from the AppImage using --appimage-mount and put it in the same folder as the AppImage. To save you the trouble, I attached obsidian.png at the bottom of this post.

I have basically the same setup, but the step above is not needed imo (Ubuntu 18.04, ymmv)
